A 4-year-old male neutered Labrador Retriever with severe gastrointestinal signs, but no respiratory signs, was diagnosed with multifocal pyogranulomatous gastritis, enteritis, and lymphadenitis with intralesional hyphae and multifocal pyogranulomatous pneumonia with intralesional yeast. Based on cytologic evaluation, histologic examination with special stains, and immunohistochemical analysis of tissues collected antemortem or at necropsy, dual infections with Pythium insidiosum and Blastomyces dermatitidis were detected and are reported for the first time.

The pathogenic oomycete Pythium insidiosum causes a fatal infectious illness known as pythiosis, impacting humans and certain animals in numerous countries in the tropics and subtropics. Delayed diagnosis is a primary factor contributing to the heightened morbidity and mortality associated with the disease. Several new serodiagnostic methods have been developed to improve the identification of pythiosis.

Pythiosis, a rare and formidable infectious disease caused by , is characterized by profound uncertainties in achieving definitive diagnoses, suboptimal outcomes, and an exceptionally high mortality rate. Here, we present a rare case of human spinal pythiosis in southern China. With advanced metagenomic sequencing technology, was pinpointed as the causative pathogen.

Pythiosis is caused by the oomycete Pythium insidiosum. Within the United States, Pythiosis is most seen in the Southeast and Gulf Coast states, but it has an expanding distribution. Pythiosis is characterized by gastrointestinal or cutaneous lesions, and rarely these lesions are seen together.

Pythiosis, caused by Pythium insidiosum, is an infectious and non-transmissible disease affecting horses, dogs, and humans, with no effective drug treatment available. Triazoles are compounds of interest for their potential pharmacological properties against fungi and bacteria. In this study, we synthesized three new triazole compounds (C1, C2, and C3) to assess their in vitro activities against P.

For more than 100 years, the infections caused by have been well documented in horses. However, recently, pythiosis was also described in several species, including dogs, cats, cattle, zoo captive animals, and humans. Human pythiosis is a life-threatening infection requiring an early diagnosis for a successful management.
